What causes an overlapped image?

Inadequate film processing
Improper horizontal angulation
Excessive tube angulation
Not using a film holder

The correct answer is: Improper horizontal angulation

An overlapped image is primarily caused by improper horizontal angulation during the radiographic procedure. When the X-ray tube is not positioned correctly in relation to the film or sensor, it can result in the overlapping of structures in the image. This typically occurs when the X-ray beam is angled inappropriately, causing multiple anatomical structures to be superimposed over one another, leading to a loss of clarity and diagnostic quality. Proper horizontal angulation is crucial for obtaining clear and distinct images that accurately represent the anatomical areas being examined. When the angle is wrong, it can significantly distort the resulting image, making it difficult for healthcare professionals to interpret. This is why the correct choice centers on the importance of proper angulation in radiographic technique.
